Twice baked potatoes in casserole form!

Today’s recipe is one I tried last month knowing it would be great for fall and especially for a Thanksgiving side dish. It’s a Twice Baked Potato Casserole that was DELICIOUS!! If you have ever had Twice Baked Potatoes before then you can imagine how a casserole version would be so good.

The family agreed that this easy casserole dish is just as good or even better than twice baked potatoes. I agree it was great but still can’t decide which is better. I love that both are easy to make, but loved the simplicity of throwing it all in a dish as opposed into each potato skin. I also have a thing for red potatoes so this casserole is a new favorite.

As you could venture to guess, this casserole is called twice baked because the potatoes get baked twice. Baking them the first time allows them to be cooked all the way and to be cooked until soft. We have a feeling you will love this recipe as much as we do!

How to make Twice Baked Potato Casserole:

Potatoes: I like using red potatoes for this casserole because they keep their shape and texture a little better than russet potatoes. Another reason I like using red potatoes is that you do not need to peel them first. However, you can use russet potatoes if that’s what you have on hand or prefer. 

This is a great recipe to make when you have leftover baked potatoes. You can also use boiled potatoes, If you’re in a hurry you can even use cubed freezer potatoes. 

For this recipe, we cut them into 1 inch cubes after being baked. We also put together a mixture of sour cream, salt, pepper, bacon and cheese. Then this is layered in a 9×13 dish with the potatoes.

The casserole gets baked again allowing for the cream mixture to get heated through and the result is a cheesy, hearty potato casserole that everyone goes nuts for!

Change it Up + storing

Variations: There are several ways to change up this casserole. Here are a few ideas…

  • Replace or mix the bacon with ham cubes or sausage chunks.
  • Mix in veggies corn, broccoli florets or diced bell peppers would all add a delicious twist.
  • Sour cream: greek yogurt is a close substitute. You can also use an equal amount of heavy whipping cream  mixed with 1tbsp lemon/lime juice per cup used.
  • Add or subtract the amount of sour cream used to your liking. 

Leftovers: Divide leftovers into individual containers, keep in the fridge for 1-2 days. 

Reheat: If you are only reheating an individual portion you can use the microwave. Heat in 30 second increments until hot. For larger portions preheat the oven to 350°F for 20-30 minutes depending on the size until hot.

Ahead of time: You can make this ahead of time through step 4. Cover and store in the fridge for 1-2 days before baking a second time and serving. For longer storage be sure to use a freezer safe baking dish. Wrap with plastic wrap and again with foil, Store in the freezer for up to 2 months. Thaw overnight on the fridge before baking a second time.

    I can’t wait to try these potatoes for Thanksgiving! They look delish!

  2. Lynn says:

    Are those chopped chives I see in the photo? You don’t mention any toppings in the recipe. If they are, I think that would be a great addition.

    1. Lil'Luna Team says:

      Yes, you are welcome to top with any garnishes that you like. The chives give it a fun little pop of color too! Definitely a fun addition if your family would enjoy them!

    This was amazing. I had to substitute Monterey Jack cheese for the Mozzarella, because I thought I had a 3 Cheese Italian Blend that I planned to use, but when I went make it, I realized it was not an Italian Blend but Monterey instead. It still tasted wonderful. I also added more bacon on top after cooking, along with chopped parsley, but I mean who doesn’t want MORE bacon!!

    1. LilLunaTeam says:

      I feel the same way! You can never have too much bacon. 🙂 Thanks so much for sharing what you did. I’m so happy it turned out so tasty!

  4. Emily Martinez says:

    Looking forward to making this for Easter brunch this weekend! Any tips on making it ahead of time? Would the baking time be the same? Would you suggest letting it sit out for a certain amount of time before baking? Can’t wait to try it, looks delish!!

    1. LilLunaTeam says:

      You can make this ahead of time through step 4. Cover and store in the fridge for 1-2 days before baking a second time and serving. I would suggest letting it sit out on the counter for about 20 minutes or so until it comes more to room temperature before baking. You can keep the same baking time. Hope this helps! Have a wonderful Easter brunch!
